Filed August 3, 1925 pairs stares rarer CHARLES E. LUGKE, OF NE? YOIE-lli, N. Y., ASSIGHOR TO \VORTHZNGTON PUMP AND MACLEIENERY COBPGRATION, OF NEW YORK, N.'Y., A CORPORATION OF VIRGINIA.-

CONDENSING APPARATUS.

Application filed August to the boiler containin air or gases.

The object of the invention is to provide a combined surface condenser and surge tank, enabling the system to be made more compact and greatly cheapened, while at 13 the same time securing important advanta es, especially in the absence of piping and consequent friction in the usual surge tank connections, the use of a single foundation for both the condenser and surge tank,

so the open and free connection between the surge tank and vacuum space of the condenser, and the heating of the condensate in the surge tank.

lln accordance with the invention, the surlace condenser and surge tank are combined in a single structure, with the surge tank open to the vacuum space of the condenser, and preferably the condenser is enclosed within the surge tank casing andsurrounded by the water in the surge tank. Some of the advantages of my invention, however, may be obtained by constructionsin which the surge tank is mounted within the condenser casing.

at For a full understanding of the invention, 7

a detailed description of constructions embodying the same in preferred forms will now be givenin connection with the accompanying drawings in which such construc- 4o tions are illustrated, and the features forming the invention will then be specifically pointed out in the claims.

in the drawings Figure 1 is a diagrammatic section of a combined condenser and surge tank of a preferred form, with the condenser mounted in the surge tank;

Figure 2 is a side view of the same partly in section on the line 22, looking to the left in Fig. 1;

Figure 3 is a view similar to Fig. 1, showing a modified form of construction, with the condenser within the surge tank, and

ing a surge tank mounted centrally in the condenser shell.

Referring to the drawings, and especially to Figs. 1 and 2, A is the exhaust inlet, 13 the surge tank shell, shown as of rectangular form, C the condenser casing within the Fi'urge tank, the condenser being shown as of a type having the tube bank 11 arranged in convolutions for steam distribution and condensation and as having the air cooling chamber 12 and air off-take 13, the usual hot-well 1 at the bottom of the condenser being provided, as shown, connected by pipe 15 to ot-well pump 16, which delivers the condensate to the surge tank through pipe 17. The hot-well is shown as provided with a valve 1 controlled by float 2 in the hotwell, so as to admit water from the surge tank to the hot-well when the level ofthe water therein falls, so as to maintain a body oi water on the suction side of the pump 16 for sealing and priming the latter. The makeup water is admitted to the surge tank through pipe 18, the latter being normally closed by valve 3 and opened for the supply of make-up water, when the water in the surge tank falls below the desired level, under the control of float 1 in the surge tank. The water is discharged from the bottom of the surge tank through pipe 19 connected, as usual, to the boiler feed system, either with or without degasiiiers and heaters. i

In the preferred construction of combined condenserand surge tank, as shown in Fig. 1, the'surge tank encloses only the condensing chamber of the condenser, the water chambers 20, 21 of the condenser extending outside the surge tank for simplicity of connection and ready access tothe water chainbers and connections. This construction also provides for the heating of the surge tank water by the heated condenser shell and exhaust steam, without any cooling effect from the circulating water chambers, as would be the case it these were enclosed within the surge tank. The surge tank casing 13 and the condenser casing G are supported, one on the inner side and the other on the outer side, by the beams'22, which are shaped to fit around the condenser and surge tank casings, these beams being of such number and made of such strength as to support the casings in such a manner as to sustain the pressure on the surge tank.

I retaining A the invention .annular surge tank chamber between the two casings, the casings of thin sheet metal being supported by a number of circular beams between them which preferably are made in complete circles passing across the steam inlet A, and provided with openings 4 through them to permit the circulation of water throughout the surge tank.

In Figure 4 there is shown a construction in which the surge tank B is mounted centrally within the condenser, the condenser tubes 11 being shown as arranged in two groups on opposite sides of the surge tank.

In this construction, the condenser casing is, as shown, of octagonal form, with the casing supported on the inner side by brac-' ing frames 23 arranged at such intervals as to permit light sheet metal to be used for the condenser casing.

It will be understood that is not to be limited to. the specific form or arrangement of anyfof the constructions shown,.but that various modifications may be madeby those skilled in the" art, w-hile defined by the claims.

lVhat isclaimed is:

'lfA combined steam condenser and con- [densate surge tank for condensing systems within a single casing.

2. A combined steam condenser and condensate surge tank for condensing systems within a single casing, said surge tank having a steam space above the water providing for free admission and escape of steam from above the water surface.

3. A combined steam condenser and condensate surge tank for condensing systems within asingle casing, with the surge tank open to the condensing space,

the invention neoepae tank, an inner casing within the surge tank casing enclosing the condensing chamber, said casings beingmade of sheet material, and metal shapes between and supporting said casings, said metal shapes being of such strength and spaced at such intervals as to permit'light sheet material to be used for the casings.

7 for condensing systems, having the condenser and surge tank enclosed in'a single casing, a hot-well below the condenser, in combination with a condensate pump and connections for delivering the condensate from the hot-well to the surge tank.

8. A combined condenser and surge tank for condensing systems, having the condenser and surge tank enclosed in a single casing, a hot-well below the condenser, in combination with a condensate pump and connections for delivering the condensate from the hot-well to the surge tank, and a fioatecontrolled connection from the hotwell to the surge tank for maintaining a desired water level in the hotwell.

9. A combined condenser and surge tank for condensing systems, having the condenser and surge tank enclosed in a single casing, a hot-well below the condenser, in combination with a condensate pump and connections for delivering the condensate from the hot well to the surge tank, a float-controlled connection from the hot-well to the surge tank for maintaining a desired water level in the hot-well, and fioat controlled make-up water connections to the surge tank.

In testimony whereof, I have hereunto set my hand.
